Five people including an off-duty police officer were killed Thursday in Raleigh, North Carolina, after a 15-year-old suspect went on a shooting rampage and later barricaded himself inside a residence.

The teen suspect has not been identified, but is currently in the hospital in critical condition. A motive for the shooting is not known. It’s also not known what kind of injuries led to the suspects hospitalization, the New York Post reports.

According to a witness, the suspect had a “long-barrel shotgun and was dressed in camo.”

“He had a full backpack on that was also camouflage,” the witness said.

“We’re standing with you in this moment of unspeakable agony,” Gov. Roy Cooper during a press conference. “No one should feel this fear in their communities. No one. As policymakers, we cannot, and we will not, turn away from what has happened here.”

K-9 Officer Casey Clark was wounded during the incident but has since been treated and released from the hospital. Surviving victim Marcille Gardner, 59, remains in critical condition.
